M&D designs Racing is pleased to announce the introduction of the

New M&D designs Cast 254 (25.4cc)

Many of the new Cast 254 engines have left the workshop. At this time, I am shipping the motors as I receive them from the honing process. If you have preordered, I will be contacting you when I have one ready to ship. As I will be following the preorder list I have, please be patient (as I know you have been) and I shall be moving through the orders as quickly as I can. Do not send payment if you are on the list unless you have been directly contacted by me.

Thanks again. 

Matthew Waldron
